LAGOS, Jan 6 (Reuters) - A Nigerian militant group, which has claimed attacks on oil pipelines in the Niger Delta, said in a statement on Friday that it had asked its fighters to prepare to fight the “enemy” as authorities were not ready for dialogue.

“It has been evidently clear that the Nigerian state is not ready for any form of dialogue and negotiation,” the Niger Delta Avengers said in a statement posted on its website. (Reporting by Vishal Sridhar and Ulf Laessing, editing by G Crosse)
